基于 yiisoft/yii2-app-advanced，在 GitHub 上新建仓库 yii2-app-advanced，新建接口应用(实现 RESTful 风格的 Web Service 服务的 API)，调整默认字符集为：utf8mb4，接口响应格式的调整，空数组自动转换为空对象，在接口应用中收集请求日志消息(1个请求对应1条日志消息)至数据库，且实现日志功能的相应接口：日志列表(设置数据过滤器以启用筛选器处理)、日志详情（二）
1、在开发环境中，执行数据库迁移命令失败：1071 Specified key was too long; max key length is 767 bytes，如图17

2、在开发环境中的数据库中运行SQL，报错：#1071 – Specified key was too long; max key length is 767 bytes，如图18
图18
3、如果使用的是utf8mb4，并且在长度超过191个字符的varchar列上有唯一索引，则需要打开innodb_large_prefix以允许索引中的较大列，因为utf8mb4需要比utf8或latin1更多的存储空间。如果启用innodb_large_prefix（默认值），则对于使用DYNAMIC或COMPRESSED行格式的InnoDB表，索引键前缀限制为3072个字节。如果innodb_large_prefix被禁用，则任何行格式的表的索引键前缀限制为767字节。在本地环境执行迁移命令成功，是因为本地环境的MySQL版本为5.7.19(MySQL 5.7.7 默认启用innodb_large_prefix，Innodb_large_prefix在MySQL 5.7.7中已弃用，并将在未来版本中删除。)，而开发环境为 5.6.16，查看网址：https://dev.mysql.com/doc/refman/5.7/en/innodb-restrictions.html ，如图19
图19
4、阿里云RDS的参数配置，启用Innodb_large_prefix，如图20
图20
5、在开发环境中的数据库中运行SQL，成功，如图21
图21
ALTER DATABASE `pcs-api-dev` CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci
ALTER TABLE pa_user ROW_FORMAT=DYNAMIC
ALTER TABLE pa_user CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci
注：一些数据库还可能需要运行
set global innodb_file_format = BARRACUDA;
6、编辑数据库迁移文件，\console\migrations\m180620_105204_update_table_options_to_log.php
<?php
use yii\db\Migration;
/**
* Class m180620_105204_update_table_options_to_log
*/
class m180620_105204_update_table_options_to_log extends Migration
{
/**
* {@inheritdoc}
*/
public function safeUp()
{
$tableOptions = null;
if ($this->db->driverName === 'mysql') {
// http://stackoverflow.com/questions/766809/whats-the-difference-between-utf8-general-ci-and-utf8-unicode-ci
$tableOptions = 'CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ENGINE=InnoDB';
$this->execute('ALTER TABLE {{%user}} ROW_FORMAT=DYNAMIC');
$this->execute('ALTER TABLE {{%user}} CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci');
$this->execute('ALTER TABLE {{%log}} ROW_FORMAT=DYNAMIC');
$this->execute('ALTER TABLE {{%log}} CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci');
}
$this->addCommentOnTable('{{%user}}', '用户', $tableOptions);
$this->addCommentOnTable('{{%log}}', '日志', $tableOptions);
}
/**
* {@inheritdoc}
*/
public function safeDown()
{
echo "m180620_105204_update_table_options_to_log cannot be reverted.\n";
return false;
}
/*
// Use up()/down() to run migration code without a transaction.
public function up()
{
}
public function down()
{
echo "m180620_105204_update_table_options_to_log cannot be reverted.\n";
return false;
}
*/
}
7、配置请求日志允许记录的请求方法，主要是忽略 GET 请求的日志，编辑 \api\config\params.php
<?php
return [
'adminEmail' => 'admin@example.com',
'requestLog' => [
'allowMethod' => ['POST', 'PUT', 'DELETE'], //请求日志允许记录的请求方法
],
];
8、在 Postman 中，GET http://api.pcs-api.localhost/v1/logs?login_id=e56db1b43546a110431ac38409ed8e9e&login_tid=49117dc410c491af0de08f2948aecd8f&page=2

[…] 20、参考：阿里云RDS的参数配置，启用Innodb_large_prefix 。编辑 config/database.php，修改 ‘engine’ => null, 为 ‘engine’ => ‘InnoDB’,。再次执行数据库迁移，报错。SQLSTATE[42S01]: Base table or view already exists: 1050 Table ‘failed_jobs’ already exists。在数据库中删除掉所有表后，重新执行迁移。不再报错。 […]
